Hi Mike Somewhat redacted output from a few minutes ago:

Depending on source filer load, I've seen Replication Throughput anywhere from 25MB/s through 400MB/s and higher. The source aggregate is 192x600GB SAS on a filer with 2TB FlashCache and it sometimes sees periods of 30K IOPS. I guess the point is ETA has been anywhere from just about now all the way out to this coming Sunday. There's a good chance that the move will complete before tomorrow evening according to these numbers though. If it doesn't complete on time, I guess we'll find out what effect, if any, SFO has (unless I can easily reschedule this HW maintenance).

How long did it take to get to your 60% point that you reference? Some quick math says 30TB at 400MB/s should complete in about 22 hours. If you're 60 percent done, and you have a day and a half, then it should complete before tomorrow night, right?
